Area and Perimeter of a Triangle

EXPERIMENTING WITH AREA AND PERIMETER: TRIANGLES Looking at a collection of different polygons, there are two ways to decide which is the “largest” or which is the “smallest.” One way to decide is to measure the area of each using unit squares, and then compare. Another way to decide is to measure the length of the perimeter of each, then decide.
